Characteristics1&rpar;High reliability with guaranteed &plus;&sol;-3&percnt; output power tolerence&period;2&rpar;The modules can withstand high wind-pressure&comma;snow loads and extreme temperatures&period;3&rpar;Bypass diodes to minimize power loss with shading&period;4&rpar;High and stable conversion efficiency to ensure the highest quality&period;

1&period; The important raw material&comma; Solar cells&comma; come from domestic public company and Taiwan famous company&period; Quality assurance&colon; 25 years long life span&comma; Industry leading power output warranty 10 years 100&percnt;&comma; 20 years 95&percnt;&comma; 25 years 85&percnt;&period;

There are some company which select inferior solar cells that are processed from recycled silicon material from small workshop&comma; so their solar panel service life maybe less than 5 years because inferior solar cell power reduce much more every year&period;

2&period; Our company has automated production line for solar panel&period; Good technology&comma; good quality assurance&period; Strong production ability&colon; 300 pieces 300w solar panels can be manufactured per day&period; Most of company weld solar cell with artificial manual work&period; Bad manufacturing technique is difficult to keep consistency of products&period;

If you need to know more information about 300Watts Solar panels &period;Please make a telephone for us&period;
